Final answer:
Judaism is not the second largest religious group in the world. Christianity and Islam have larger numbers of followers. Judaism is a smaller religion with around 11 to 15 million adherents worldwide.
Step-by-step explanation:
No, Judaism is not the second largest religious group in the world. Christianity is the largest religion with around 2.2 billion adherents, followed by Islam with approximately 1.8 billion followers. Judaism, on the other hand, is a much smaller religion, with an estimated 11 to 15 million people identifying themselves as Jewish worldwide. While Judaism is an influential and important faith, it does not have the same level of global prominence as Christianity and Islam.
